Problems solved by technology

Due to the limited radio spectrum resources, if a constellation system is completed before other systems, and the subsequent system is not allowed to use the occupied frequency resources, it will cause a great waste of satellite radio spectrum resources, and it will be extremely unfavorable to latecomers. Fairness; when multiple NGSO systems exist at th...

Embodiment 1

[0031] Each satellite in the constellation communication system provides access and business uplink and downlink transmission channels for each user terminal through the user link constructed by the radio beam, and accesses the gateway station through the feeder link (or performs routing transfer via the inter-satellite link Then access the gateway station through the feeder link), and then realize the interconnection with the ground communication network through the gateway station. Both the user side and the feeder side need to use radio spectrum resources, and the user side is divided into signaling frequency bands and service frequency bands. The specific division is shown as follows figure 1 shown.

[0032] Such as figure 2 As shown, the embodiment of the present invention provides a method for realizing the compatible coexistence of the new and existing NGSO constellation communication systems, including:

Abstract

One embodiment of the invention discloses a method for realizing compatible coexistence of a newly-built NGSO constellation communication system and an existing NGSO constellation communication system. The method comprises the following steps that a satellite of the newly-built NGSO constellation communication system performs control-level signaling interaction with a ground user station through afirst signaling beam, wherein the combined coverage range of the signaling beam of each satellite in the newly-built NGSO constellation communication system ensures that at least one re-coverage range is realized on the earth surface; a newly built NGSO constellation communication system satellite performs service communication with the ground user station through a first user beam, wherein a spot beam of each satellite is controlled to point to different wave positions in different time slots, the fixed wave position forms a first range, and the first range is consistent with the re-coveragerange; and the ground user station acquires current available spectrum resources, and sends position information and spectrum occupation information to the satellite covering the user station throughthe first signaling beam.

Description

technical field [0001] The invention relates to the field of satellite communication. More specifically, it relates to a method for realizing compatible coexistence of newly built and existing NGSO constellation communication systems. Background technique [0002] In recent years, many companies at home and abroad have proposed a low-orbit satellite Internet constellation system that can provide data services and realize Internet transmission functions. This type of satellite communication constellation system includes the following characteristics: From the perspective of constellation scale, it consists of hundreds A giant constellation composed of satellites; from the perspective of constellation composition, most of them are composed of small satellites operating in low earth orbit (LEO). According to the current satellite network data declaration status of various satellite Internet companies in the International Telecommunication Union (ITU), several satellite communi...
